' or OKLAHOMA CITY, OKLAHOMA APPARATUS FOR REGULATING TEMPERATURES IN BUILDINGS Application filed October 5, 1931.. Serial 1%. 567,080.

This invention relates to apparatus for regulating temperatures in buildings and it is more especially an improvement upon the apparatus disclosed in my Patents 1.681.995

warm Weather cool clean air can be supplied to the building through conduits and fiues' which, at other times, are employed for distributing heated air.

Another object is to utilize a supplemental air supply for furnishing heated filtered air to the interior of the building in which a circulation of warm air is taking place,

A further object is to filter fresh air and cool it by 'a simple and effective means which is accessible readily for cleaning and repairs.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has beenshown.

Y 7-7, Figure 6.

Figure 4 is a section on line 4-'-4, Fig- Referring to the figures by characters of reference, 1 designates a'chimney structure containing a flue 2 and formed in this structure at the sides of the flue but out of 'com-, munication therewith are cooling chambers 3 each of which has an outside door 4 whereby access thereto may be had readily. 1

A mantel 5 is erected in the building A across the inner side of chimneyl and is pro vided in its top with the grating 6 through which the flow of air can be controlled by pivoted slats 7' operated by any suitable means. 1

An air box 8 is located below the floor level 9 and beneath a fire box or combustion chamber 10 built into the mantel. This fire box'*has a grate 11 for supporting fuel and an air inlet 12 having a damper 13, supplies air beneath the grate tq support combustion. The front of the fire box can be closed by a door or the like indicated generally at 14 .and which can be like that shown in my Patent 1,681,995.

Spaced outlet flues 15 are inclined upwardly from the fire box to the flue 2 in chimney 1 and are providcd'with dampers 16 adapted to. be opened or closed by a rod 17. An inlet for air can be provided in the front of the mantel above the fire box as at 18 and has a series of dampers 19 for controlling the flow. This allows air from the room to be reheated and then delivered through grating 6.

The air box 8.0pens upwardly into an air chamber 20 which extends across the back, sides and top of the fire box but is out of communication therewith. Thus fuel burned on the grate will heat air in chamber 20 from which it can escape through the outlet 6 into the adjacent room B in the building A. The floor of this room containsanv outlet grating21opening into anair flue 22 which leads to the air box 8. These gratings 21 and 23 can beof the usual type for use with air heating systems,

there being dampers shiftable by toot or otherwise by means of which the gratings can be opened, oigclosed to control the free flow of air through the several rooms. In cold-weather the gratings can be regulated to cause warm air to flow to any room or rooms desired while in warm weather the gratings can be regulated to causedesired rooms to be cooled. As the several rooms communicate through door openings and through wall gratings 26 a circulation .of

warm air through the entire structure can be effected.

Water containers 27 can be located in the sides of the mantel for supplying moisture to the air being heated. These are kept filled by float controlled water inlet valves 27 The structure thus far described does not differ greatly from that already patented by me. The present improvements include a means for filtering and heating fresh air to be supplied to the building to mix with the circulating air, and a means for filtering and cooling fresh air to be supplied to the building.

The fresh air heatingmeans includes a metal flue 28 supported in the flue 2 and having an outside air inlet 29 and an inside air outlet 30. At the inlet'there is provided a grating 31 back of which is provided a screen 32. A mineral wool or other filtering material 33 is interposed between the grating and screen and is supplied with an oil or other suitable fluid, through apertures formed in the bottom of a reservoir 34. A trough 35 is'located beneath the filtering material for receiving the fluid draining therefrom and this can have an outlet 36 leading to a sewer.

The outlet 30 is located near the ceiling of the room B and can be partly or entirely closed by a damper 37. 'Another damper 38 can be located in flue 28 and operated by a rod 39 and lever and rod connections 40 and 41 as shown.

Vitiated air can be vented into the chimney through an outlet 42'having .,a damper 43 lior the purpose of'supplying cool clean air to the rooms of the building A, each of the air cooling chambers 3 is provided. These chambers open near their lower ends through outlets 44 into the air box 8 and are also provided near their lower ends in their outer walls with inlets 45 for fresh air. Each inlet can have a damper 46 for controlling the flow of air' therethrough.-

The bottom of each chamber 3 is formed of a deep water pan 47 having an overflow 48 near the top thereof opening into a pipe 49 leading to' asewer or other outlet;

Each compartment is divided by a central partition 50 into an inlet side 51 and an outlet side 52 both of which communicate througha top or intermediate chamber 53. The lower end of the partition 50 extends below the level of water in pan 47- so that air can flow from the inlet 45 to outlet 44 solely by way of the portions 51 and 52- of the compartment and the intermediate chamber 53.

Upper and lower pairs of parallel angle strips 54 are secured in chamber 3 and engage and support the corner portions of frames 55 each of which is wrapped with a thin fabric 56 such as gauze. Clips 57 grip the fabrics to the tops of the frames and said frames are held assembled atv proper distances by rods 58 extending therethrough and having spacing sleeves 59 or the like.

A spraying head 60 is supported in chamber 53 and is supplied with water under pressure so that a mist Will be produced in said chamber in the path of the current of air flowing to the outlet 44. 1 For the purpose of producing a forced draft of either warmed or cooled air, a re- 1 during Warm weather water is sprayed from heads 60, dampers 46 and 62 are opened, dampers 7 and 19 are closed, and fan 61 is actuated to draw air from the inlets 45 through compartments 3 to outlets 44 and then into flue 22 from which it is distributed to the several floor grates. The water delivered from heads 60 will saturate the panels, formed by frames 55 and their fabric coverings and as the air must flow along the panels and through the mist in chamber 53 it will be quickly and effectively cooled before it enters box 8. The used air can leave the building through outlet 42 or any other desired place.

Dampers 62 are provided for controlling the flow of filtered air through the outlets 44, these dampers being operated by'rods63' or the like. I v

For the purpose of .supplying chilled-air to the rooms supplemental cooling means can be provided in the form of mechanical refrigerating units 64 supported in the adjacent to the chimney if desired, however,-

itcan be located outside of and separated from the building 'in which event it will be connected to' air box 8 by a suitable'conduit or flue in any obvious manner.

The present apparatus serves to remove moisture from the air brought into the buildg the flow of and the interior of said structure, a heater ing; to remove dust and disease-carrying germs from the air brought into the house during the winter months; and warms the fresh air during the winter months after it has been filtered and before it is delivered into the house.
